SAME PLAGE.

IMPROVEMENT IN SHEET-METAL CANS.

Specification forming part of Letters PatOnLNO. 207,007, dated August 13, 1878; application filed February 1, 1878v .Toall whom fit 'may concern:

Be it known that I, GEORGE D. BROOKs, of the city of Baltimore and State ot' Maryland, have invented certain Improvements in SheetMetal Gans, of which the following is a specification 5 and I do hereby declare that in the same is contained a full, clear, and exact description of my said invention, reference being had to the accompanying drawing, and 'to the letters of reference marked thereon.

The invention consists in a cylindrical canbody having each of its ends expanded or shaped into an angular bead, combined with heads having their edges flanged or iiared outwardly to a size of about equal diameter with the center or vertex ofthe said angular beads, the downward iiange of each head resting in an expanded end ot' the can, which, when the can is sealed, is bent over and against the liange of the head from the center or vertex of the bead, as hereinafter described.

In the further description of the invention which follows, reference is made to the accompanying drawix'lg, forming a part hereof, and in which- Figure lis a vertical section of the case with the heads inserted therein previous to the contraction of the expanded edges of the canbody. Fig. 2 is a similar section of the completed can.

Similar letters of reference indicate similar parts in both figures.

A is the body of the can, having the angu-4 larly-beaded or radiallylistended ends a. B B are the iianged heads of the can, adapted for insertion in the distended ends of the body,

as shown in Fig. l of the drawing. `PreviousY to the soldering of the heads to the body the distended edges of the body are contracted by means of suitable machinery, so as to present the appearance shown in Fig. 2 of the draw- 1n g.

The advantages of contracting.;` the edges of the can-body over and upon the heads, as described and shown, consist in that the heads are securely held in place during the soldering operation, and the joints are so thoroughly closed that no admission of solder to the interior of the can can possibly take place, thus preventing injury to the contents from contact with solder, two-thirds of which is usually lead.

A further advantage consists in that less solder is required to effect water and air tight joints, there being,'practically, no space between the flanges of the heads and the body to be closed by the melted solder. y

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent of the United States, is-

The can body A, having the angularlyn beaded ends a, combined with the heads B, having their edges bent downward at an obtuse angle, each of said heads being placed in an angular bead of the body, and secured therein by the overlapping of that portion of the bead beyond the vertex of the angle forming the bead, substantially as herein specified.

In testimonyywhereof I have hereunto subscribed my name this 12th day of anuary, in

the year of our Lord 1878. y eno. D. Baoons. Witnesses: Y
